The Dacron cuff on tunneled catheters promotes fibrous tissue ingrowth that mechanically anchors the catheter and creates a barrier against microorganism migration along the tunnel.

Question 65: A post-mastectomy patient requires vascular access. Which assessment finding from the history should most directly guide site selection?

• Whether an axillary lymph node dissection was performed on one or both sides (Correct answer)
• The type of chemotherapy agents previously received
• Current upper extremity range of motion
• The date of the most recent mammogram

Correct answer: Whether an axillary lymph node dissection was performed on one or both sides

Axillary lymph node dissection increases risk of lymphedema, making that ipsilateral arm contraindicated for vascular access.

Question 66: Which professional attribute is most valued in infection prevention within the VABC field?

Certification requirements evolve to keep pace with advances in professional knowledge, technological developments, and changes in practice standards. This ensures that certified professionals remain current and competent in a changing professional landscape.

Question 68: Which statement BEST describes the role of ethanol lock therapy in vascular access infection prevention?

• Ethanol lock therapy requires catheter removal for the solution to be effective
• Ethanol lock is used to dissolve fibrin occlusions and does not have antimicrobial properties
• Ethanol lock instills 70% ethanol into the catheter lumen to sterilize biofilm and is used prophylactically or therapeutically in high-risk patients (Correct answer)
• Ethanol lock is approved only for arterial catheters and not central venous catheters

Correct answer: Ethanol lock instills 70% ethanol into the catheter lumen to sterilize biofilm and is used prophylactically or therapeutically in high-risk patients

Ethanol lock therapy uses 70% ethanol dwelling in the catheter lumen to eradicate biofilm-embedded organisms and is used prophylactically in high-risk patients (e.g., pediatric oncology, home PN) or therapeutically for catheter salvage.

Question 69: A VABC certified professional is asked to provide services outside their scope of competence. The CORRECT ethical response is to:

• Accept but charge a lower rate
• Accept and learn as they go
• Decline and refer to a qualified professional (Correct answer)
• Accept the work to gain new experience

Correct answer: Decline and refer to a qualified professional

Ethical practice requires professionals to work within their scope of competence. Accepting work beyond one's qualifications can lead to substandard results and potential harm. Referring to qualified professionals ensures proper service delivery.

Question 70: What is the recommended approach when managing conflicting priorities in VABC?

• Delegate all decisions upward
• Prioritize based on impact and urgency (Correct answer)
• Ignore lower-priority items

Prioritizing based on impact and urgency ensures the most critical issues receive attention first while maintaining progress on other goals.

Question 71: Which IV solution is classified as isotonic and most closely matches the osmolarity of human blood?

• 0.9% Sodium Chloride (Correct answer)
• 0.45% Sodium Chloride
• 10% Dextrose in Water (D10W)
• 3% Sodium Chloride

Correct answer: 0.9% Sodium Chloride

0.9% Sodium Chloride (Normal Saline) is isotonic with an osmolarity of approximately 308 mOsm/L, matching plasma osmolarity.

Question 72: How should a catheter-related infection be managed?

• Increasing the dosage of fluids administered
• Removing the catheter, administering antibiotics, and monitoring for further infection
• Applying a cold compress to the infection site
• Changing the catheter dressing more frequently

Managing a catheter-related infection typically involves a multi-faceted approach to eliminate the source and treat the systemic infection. Removing the infected catheter is crucial as it often serves as the nidus for bacterial growth, making antibiotic treatment alone less effective. Concurrently, appropriate antibiotics are administered to combat the infection throughout the body. Continuous monitoring is then essential to ensure the infection resolves completely and to detect any signs of recurrence or further complications.

Question 73: Which professional attribute is most valued in pediatric access within the VABC field?

• Avoiding challenging situations
• Accountability and commitment to standards (Correct answer)
• Prioritizing personal convenience
• Working in isolation

Correct answer: Accountability and commitment to standards

Accountability and commitment to professional standards build trust and ensure consistent, high-quality practice.

Question 74: Which anatomical triangle contains the femoral artery, vein, and nerve, and is used as a landmark for femoral vascular access?

• Petit's triangle
• Adductor (subsartorial) canal
• Hesselbach's triangle
• Scarpa's triangle (femoral triangle) (Correct answer)

Correct answer: Scarpa's triangle (femoral triangle)

The femoral triangle (Scarpa's triangle) is bounded by the inguinal ligament, sartorius, and adductor longus muscles and contains the femoral nerve, artery, and vein.

Question 75: According to SHEA/IDSA guidelines, which practice is recommended to reduce CLABSI rates in ICU settings?

• Restricting central line access to attending physicians only
• Routine guidewire exchange of central lines every 72 hours
• Applying bacitracin ointment to all central catheter exit sites daily
• Use of a standardized catheter insertion checklist and bundle approach (Correct answer)

Correct answer: Use of a standardized catheter insertion checklist and bundle approach

Bundle approaches with standardized checklists (hand hygiene, maximal barrier precautions, CHG skin prep, optimal site selection, daily necessity review) have demonstrated significant CLABSI reductions.

Question 76: A patient's tunneled CVC insertion site shows a small amount of clear serous drainage at the exit site that began 3 days after placement. Which assessment action is MOST appropriate?

• Culture the drainage and notify the physician of suspected infection
• Document as expected post-procedure healing and assess for signs of infection at each dressing change (Correct answer)
• Apply antimicrobial ointment without further assessment
• Remove the catheter immediately given drainage is abnormal

Correct answer: Document as expected post-procedure healing and assess for signs of infection at each dressing change

Small amounts of clear serous drainage within the first few days post-tunneled catheter insertion are a normal healing response; ongoing assessment for infection signs is appropriate.

Question 77: Which risk management approach is MOST effective for VABC professionals when evaluating potential workplace hazards?

• Delegating all safety decisions to management
• Relying solely on historical accident data
• Reactive analysis after incidents occur
• Proactive hazard identification and assessment (Correct answer)

Correct answer: Proactive hazard identification and assessment

Proactive hazard identification and assessment allows professionals to identify and mitigate risks before incidents occur, which is far more effective than reactive approaches that only address problems after they happen.

Question 78: Which finding during assessment of a patient with an implanted venous port would indicate the device requires IMMEDIATE discontinuation of infusion?

• Swelling and burning at the port site during infusion suggesting extravasation (Correct answer)
• Sluggish blood return requiring patient repositioning
• Patient reports mild discomfort with flushing
• Site has slight tenderness to palpation at the port reservoir

Correct answer: Swelling and burning at the port site during infusion suggesting extravasation

Swelling and burning at the port site during infusion are hallmark signs of extravasation, which requires immediate cessation of infusion to prevent tissue damage.

Question 79: When performing ultrasound-guided subclavian/axillary vein access, which view reduces the risk of pneumothorax compared to the traditional landmark approach?

• Subcostal approach with steep needle angle
• Infraclavicular long-axis view targeting the axillary vein (Correct answer)
• Parasternal view with probe over the clavicle
• Supraclavicular short-axis view

Correct answer: Infraclavicular long-axis view targeting the axillary vein

The infraclavicular long-axis approach targeting the axillary vein allows real-time needle visualization and keeps the needle path away from the pleura, reducing pneumothorax risk.

Question 80: When using the DIVA (Difficult Intravenous Access) score to assess a patient, which combination of factors results in the highest risk classification?

• Non-visible and non-palpable veins, history of multiple failed IV attempts, IV drug use history (Correct answer)
• Visible veins, no prior IV access issues, normal BMI
• Requires frequent blood draws, history of chemotherapy, moderate obesity
• Single prior failed IV attempt, slightly overweight, visible but small veins

Correct answer: Non-visible and non-palpable veins, history of multiple failed IV attempts, IV drug use history

Non-visible, non-palpable veins combined with prior failed attempts and IV drug use history yield the highest DIVA score, indicating greatest difficulty.

Question 81: In a pediatric patient, which characteristic of a vein makes it a POOR choice for PICC insertion?

• Straight course with no valves visible on ultrasound
• Vein located in a joint flexion area (Correct answer)
• Large diameter relative to catheter size
• Vein visible and palpable without ultrasound

Correct answer: Vein located in a joint flexion area

Veins located at or near joint flexion areas increase the risk of catheter kinking, occlusion, and damage with limb movement.

Question 82: Which patient population is at HIGHEST risk for developing a catheter-related fungal bloodstream infection?

• Ambulatory patients with implanted ports accessed monthly
• Pediatric patients with short-term peripheral IVs
• Immunocompromised patients on broad-spectrum antibiotics receiving total parenteral nutrition (Correct answer)
• Elderly patients with diabetes receiving oral antibiotics

Correct answer: Immunocompromised patients on broad-spectrum antibiotics receiving total parenteral nutrition

Immunocompromised patients receiving broad-spectrum antibiotics and TPN are at highest risk for Candida CRBSI due to disrupted normal flora, impaired immunity, and a high-nutrient intraluminal environment.

Question 83: What is the recommended maximum number of days a peripheral IV catheter should remain in place in adults before elective rotation to a new site?

• 72–96 hours (Correct answer)
• 7 days
• 48 hours
• 24 hours

Correct answer: 72–96 hours

CDC guidelines recommend replacing peripheral IV catheters every 72–96 hours in adults to reduce the risk of phlebitis and infection.

Question 84: When assessing a pediatric patient for peripheral IV placement, which vein site should be AVOIDED in neonates unless no other option exists?

• Dorsal hand veins
• Footveins distal to the ankle (Correct answer)
• Scalp veins
• Antecubital veins

Correct answer: Footveins distal to the ankle

Foot veins distal to the ankle pose risk of tissue necrosis and should be avoided in neonates unless no other site is available due to poor collateral circulation.

Question 85: What factors should be considered during the patient assessment for vascular access device insertion?

• Vein condition, medical history, and expected therapy duration should all be considered (Correct answer)
• The patient’s diet should be considered
• Only the patient's age and weight are relevant
• Only vein size should be considered

Correct answer: Vein condition, medical history, and expected therapy duration should all be considered

During the patient assessment for vascular access device insertion, several factors must be considered, including vein condition, the patient's medical history, and the expected duration of therapy. These elements collectively inform the decision-making process, helping to select the most appropriate device, insertion site, and technique. A holistic assessment ensures patient safety, optimizes device longevity, and supports effective treatment delivery.

Question 86: What is the purpose of performing daily 'line necessity' reviews for central venous catheters?

• To document catheter patency and flow rates for billing purposes
• To schedule routine guidewire exchanges every 5 days
• To assess for thrombosis with bedside Doppler ultrasound
• To ensure catheters are removed promptly when no longer clinically needed, reducing infection risk (Correct answer)

Correct answer: To ensure catheters are removed promptly when no longer clinically needed, reducing infection risk

Daily necessity reviews are a core CLABSI bundle element; prompt removal of unnecessary catheters is one of the most effective ways to reduce infection risk.

Question 87: A patient develops pinch-off syndrome with a PICC line. Which finding on chest X-ray is most indicative of this complication?

• Compression of the catheter between the clavicle and first rib (Correct answer)
• Catheter kinking at the insertion site
• Catheter tip migration to the right atrium
• Fibrin sheath formation around the catheter

Correct answer: Compression of the catheter between the clavicle and first rib

Pinch-off syndrome occurs when the catheter is compressed between the clavicle and first rib, visible on X-ray as a narrowing or angle change in that region.

Question 88: During a vascular access assessment, the nurse notes that a patient receiving peripheral parenteral nutrition (PPN) has a VAS (Visual Analog Scale) pain rating of 4/10 at the IV site. What is the PRIORITY assessment?

• Obtain a physician order to convert to central venous access
• Inspect and palpate the IV site for signs of infiltration or phlebitis (Correct answer)
• Slow the infusion rate and reassess in one hour
• Administer analgesic medication per order

Correct answer: Inspect and palpate the IV site for signs of infiltration or phlebitis

Pain at a PPN infusion site warrants immediate site inspection and palpation to rule out infiltration or phlebitis before any other intervention.

Question 89: When a patient experiences sudden onset of dyspnea, chest pain, and hypotension during central line tubing change, air embolism should be suspected. What is the IMMEDIATE positioning intervention?

• Left lateral decubitus (Durant's maneuver) with Trendelenburg positioning (Correct answer)
• Right lateral decubitus with legs elevated
• Prone position with arms at sides
• Semi-Fowler's position with head elevated 30 degrees

Correct answer: Left lateral decubitus (Durant's maneuver) with Trendelenburg positioning

Left lateral decubitus with Trendelenburg (head down) positions the air bubble in the right ventricle apex, preventing it from entering the pulmonary circulation.

Question 90: A patient's PICC insertion site shows erythema, warmth, and purulent drainage 10 days post-insertion. The FIRST priority action by the vascular access nurse is to:

• Notify the provider and prepare for catheter removal (Correct answer)
• Apply a topical antibiotic ointment and re-dress the site
• Obtain a blood culture from a peripheral vein only
• Flush the catheter with heparinized saline to clear any clot

Correct answer: Notify the provider and prepare for catheter removal

Signs of local infection with purulent drainage indicate a likely infected catheter, requiring prompt provider notification and evaluation for removal.

Question 91: Which anatomical landmark identifies the transition from the external jugular vein to the subclavian vein?

• Angle of the mandible
• Junction with the anterior scalene muscle (Correct answer)
• Sternoclavicular joint
• Clavicle at the midclavicular line

Correct answer: Junction with the anterior scalene muscle

The external jugular vein passes over the anterior scalene muscle before joining the subclavian vein, marking this anatomical transition.

Question 92: A non-coring Huber needle is required to access which type of vascular access device?

• Tunneled Hickman catheter
• PICC line
• Midline catheter
• Implanted port (Correct answer)

Correct answer: Implanted port

Huber needles have a deflected tip that cores the silicone septum of an implanted port without removing material, preserving the septum's integrity over hundreds of accesses.

Question 93: Which risk management approach is MOST effective for VABC professionals when evaluating potential workplace hazards?

• Reactive analysis after incidents occur
• Proactive hazard identification and assessment (Correct answer)
• Relying solely on historical accident data
• Delegating all safety decisions to management

Correct answer: Proactive hazard identification and assessment

Proactive hazard identification and assessment allows professionals to identify and mitigate risks before incidents occur, which is far more effective than reactive approaches that only address problems after they happen.

Question 94: Which grading scale is most commonly documented when assessing peripheral IV phlebitis?

• Braden Scale
• Visual Infusion Phlebitis (VIP) Scale (Correct answer)
• Glasgow Coma Scale
• Infiltration Scale

Correct answer: Visual Infusion Phlebitis (VIP) Scale

The Visual Infusion Phlebitis (VIP) Scale provides a standardized 0–5 grading system for documenting phlebitis severity at peripheral IV sites.

Question 95: A patient reports a PICC line was placed 3 days ago but now has pain and swelling along the upper arm. Which assessment finding would most strongly suggest catheter-related thrombosis?

• Fever above 38.5°C
• Pitting edema of the ipsilateral arm with visible collateral veins (Correct answer)
• Decreased blood pressure in the affected arm
• Redness at the insertion site

Correct answer: Pitting edema of the ipsilateral arm with visible collateral veins

Pitting edema with visible collateral veins indicates venous outflow obstruction consistent with upper extremity DVT.

Question 96: Which precaution is MOST important when replacing IV administration sets connected to a central venous catheter used for lipid-containing parenteral nutrition?

• Replacing the tubing only when visibly soiled or when the PN bag is changed
• Replacing the tubing every 96 hours using clean technique
• Replacing the tubing within 24 hours of initiating lipid-containing PN using aseptic technique (Correct answer)
• Replacing the tubing every 72 hours regardless of PN composition

Correct answer: Replacing the tubing within 24 hours of initiating lipid-containing PN using aseptic technique

CDC and INS guidelines recommend replacing IV tubing used for lipid-containing PN or blood products within 24 hours because lipids support microbial growth more rapidly than dextrose/amino acid solutions.

Question 97: What is the value of continuing education in infection prevention for VABC professionals?

• It is primarily a social activity
• It keeps professionals current with evolving standards and practices (Correct answer)
• It is only needed for recertification
• It replaces workplace experience

Correct answer: It keeps professionals current with evolving standards and practices

Continuing education ensures professionals stay current with the latest developments, standards, and best practices in their field.

Question 98: How should an infusion nurse document verbal consent for a peripheral IV insertion when a written consent form is not required?

• Document only if the patient is a minor
• No documentation is needed for verbal consent
• Note in the medical record that verbal consent was obtained (Correct answer)
• Have the charge nurse co-sign the order

Correct answer: Note in the medical record that verbal consent was obtained

Verbal consent should be noted in the medical record to demonstrate that the patient was informed and agreed to the procedure.

Question 99: Which medication preparation would be CONTRAINDICATED for peripheral IV administration due to its osmolarity?

• Lactated Ringer's Solution (273 mOsm/L)
• 0.9% Normal Saline (308 mOsm/L)
• 5% Dextrose in Water (252 mOsm/L)
• Potassium Chloride 40 mEq in 100 mL (~800 mOsm/L) (Correct answer)

Correct answer: Potassium Chloride 40 mEq in 100 mL (~800 mOsm/L)

KCl 40 mEq in 100 mL creates an osmolarity of approximately 800 mOsm/L, exceeding the peripheral threshold and carrying significant risk of phlebitis and cardiac arrhythmia if administered too rapidly.

Question 100: When performing a pre-procedure assessment for ultrasound-guided PICC placement, which finding would lead you to select a different vein than the basilic?

• The basilic vein is located 1.5 cm deep
• A non-compressible basilic vein with echogenic material on ultrasound (Correct answer)
• The basilic vein diameter measures 4 mm
• The patient has visible basilic vein tortuosity on the ultrasound image

Correct answer: A non-compressible basilic vein with echogenic material on ultrasound

A non-compressible vein with internal echogenic material is diagnostic of existing thrombosis, contraindicating catheter placement in that vessel.
